ROS answers is moving to stackexchange, could please post your question there with the webots and ros2 tags?

You should check the Webots System Requirements to fix this problem. Webots runs fine on any fairly recent hardware. The

Following the tutorial to install ROS 2 Humble on Windows 10, I am stuck at this point where I am unable to start a basic example:

ros2 run demo_nodes_cpp talker
[ros2run]: Process exited with failure 3221226505

I am getting the exact same error from both the DOS CMD and the Windows PowerShell in both admin and user modes.

Any idea on how to debug this?

I found out the reason for this crash: my ROS_DOMAIN_ID environment variable was containing a non-integer value. Setting

Since December 2018, Webots was released as free open source software (Apache 2.0 license), so it could be another optio

Hi,

There is no such tool to my knowledge. We recently developed a python script doing the reverse operation: converting a URDF file to a Webots PROTO file, I could share it with you if you are interested.

Please note however that most of the models provided within Webots are not licensed under a free open source license. Therefore, you are not allowed to redistribute modified or converted versions of these models, unless you get the official approval of the the copyright owner to do so (copyright owners of the models distributed in Webots include Cyberbotics and various companies and individuals). Please contact me if you have questions about a specific model.

Also, it may be interesting for you: the latest version of Webots, e.g., Webots 7.4.1, include a native generic ROS interface running in all versions of Webots, e.g., Windows, Mac OS X and Linux. This means that any robot in Webots can be connected to the ROS network out of the box, without installing or recompiling anything. See the documentation on Cyberbotics web site (google for ROS Webots).
